Persocket

Persocket is a term used in computing to denote concepts organized around individual network sockets. There is no single, formal definition; rather, persocket often refers to a design principle or naming convention that assigns resources, state, or policy on a per-socket basis. The idea emphasizes locality and isolation of data and control structures for each socket rather than a shared global model.

In practice, persocket concepts appear in several contexts. In networking and operating systems, per-socket state can include dedicated buffers, queues, and protocol state that are maintained separately for each socket to reduce contention and improve performance. Per-socket resource management is commonly employed in high-performance I/O stacks to improve cache locality and reduce cross-socket traffic. On NUMA (non-uniform memory access) systems, per-socket memory and affinity policies aim to keep the thread handling a socket on the same CPU socket as its memory, minimizing latency.

Some software projects or libraries may use the term persocket as a literal component name or class to encapsulate the lifecycle and configuration of a single network connection. In such cases, a persocket object might expose per-socket settings such as timeouts, buffer sizes, protocol state, and error handling specific to that connection.

Overall, persocket is not a standardized technical term with a universal definition; it reflects a broader family of practices that optimize performance and manageability by treating sockets as distinct, localized units of resources.
